This change ensures that a request containing query parameters in the array format `someArray[]=value` can be bound into a simple array in constructors, even for cases where the array values don't have nested properties. The value resolver is directly called in the constructor case, before any mutable properties are considered or even cleared (see `WebDataBinder#adaptEmptyArrayIndices` method). As a result, we need to accommodate the possibility that the request stores array elements under the `name[]` key rather than `name`. This change attempts a secondary lookup with the `[]` suffix if the type is a list or array, and the key doesn't include an index. Closes gh-34121
